(54) Solubilizing agent and hydrosol composition obtained by using the same


(57) A solubilizing agent of the present invention comprises a polyglycerol fatty acid ester, an ester-constituting polyglycerol of the polyglycerol fatty acid ester comprising polyglycerol having a degree of polymerization of not less than 8 in an amount of not less than 70 % by weight based on the weight of the ester-constituting polyglycerol. Such a solubilizing agent capable of solubilizing an oil-soluble material such as colorants, perfumes, vitamins, anti-oxidants, preservatives, germicides or fats and oils in an aqueous solvent, and a hydrosol composition containing the oil-soluble material solubilized in the aqueous solvent.
